Overall, Postscreen is no better nor worse at stopping spam than what we've all been doing via SMTPD for many years. It simply decreases the number of SMTPD processes required to do so, hence decreasing server load and allowing more processing of legitimate mail. Postscreen is no magic bullet, it's overall "catch rate" being little different than setups without Postscreen. -- Stan
